To use Cache::Static with XML::Comma documents and stores...
1) cache_static.macro must be installed in your defs directory
(typically /usr/local/comma/defs or /usr/local/comma/defs/macros)
(make install tries to do this automagically for you as of v 0.9901)
2) add cache_static to any def you want to be
Cache::Static'able
3) start using it:
Cache::Static::get_if_same($key,
[ "file|/tmp/somefile",
"_XML::Comma|Store|test3|main" ],
"_XML::Comma|Doc|test2|main|000026" ] );
